The pie charts illustrate the proportions of electricity generated from three sources—nuclear power, fossil fuel, and hydropower—in Sweden, Vietnam, Morocco, and India in 2008.
In Sweden, nuclear power was the dominant energy source, accounting for 50% of total electricity production. Hydropower contributed 35%, while fossil fuels made up the remaining 15%. In stark contrast, Vietnam relied almost entirely on fossil fuels (75%), with hydropower supplying 25% and no nuclear power utilized.
Morocco and India both depended heavily on fossil fuels, though to different extents. Fossil fuels constituted 43% of Morocco’s electricity, alongside 55% from hydropower and a negligible 2% from nuclear power. Meanwhile, India’s energy mix was dominated by fossil fuels (65%), with hydropower at 30% and nuclear power at a mere 5%.
Overall, while Sweden prioritized nuclear and hydroelectric power, Vietnam, Morocco, and India leaned more on fossil fuels, with hydropower playing a supplementary role. Nuclear power’s usage varied significantly across the four nations.

这些饼图展示了2008年瑞典、越南、摩洛哥和印度三个电力来源（核能、化石燃料、水电）的发电占比情况。
在瑞典，核能是主要能源，占总发电量的50%。水电贡献了35%，而化石燃料占剩余的15%。相比之下，越南几乎完全依赖化石燃料（75%），水电供应25%，且未使用核能。
摩洛哥和印度都严重依赖化石燃料，但程度不同。化石燃料占摩洛哥电力的43%，水电占55%，核能仅占微不足道的2%。与此同时，印度的能源结构以化石燃料为主（65%），水电占30%，核能仅占5%。
总体而言，瑞典优先发展核能和水电，而越南、摩洛哥和印度更依赖化石燃料，水电起补充作用。四国的核能使用差异显著。

The four pie charts illustrate the proportion of electricity generated from three different sources—nuclear power, fossil fuel, and hydropower—in Sweden, Vietnam, Morocco, and India in 2008.
Overall, the patterns of electricity production varied considerably across the four countries. While Sweden and Morocco relied more heavily on cleaner energy sources, namely nuclear power and hydropower, Vietnam and India were predominantly dependent on fossil fuels.
In Sweden, nuclear power accounted for exactly half of all electricity produced, making it the only country where this source was the largest contributor. Hydropower represented 35%, whereas fossil fuels constituted merely 15%. By contrast, Vietnam relied overwhelmingly on fossil fuels, which comprised three-quarters of its total electricity generation, with the remaining 25% coming from hydropower. Notably, nuclear power played no role in Vietnam’s energy mix.
Morocco, on the other hand, depended most on hydropower at 55%, the highest figure among all four nations. Fossil fuels made up 43%, and nuclear power contributed a negligible 2%. Similarly, India was heavily reliant on fossil fuels at 65%, followed by hydropower at 30% and nuclear power at just 5%.

这四张饼图展示了2008年瑞典、越南、摩洛哥和印度四个国家从三种不同来源——核能、化石燃料和水力发电——所产电力的占比。
总体而言，这四个国家的电力生产模式差异显著。瑞典和摩洛哥更依赖核能和水力发电等清洁能源，而越南和印度则主要以化石燃料为主。
在瑞典，核能恰好占全部发电量的一半，使其成为唯一以该能源为主要来源的国家。水力发电占35%，而化石燃料仅占15%。相比之下，越南严重依赖化石燃料，其占总发电量的四分之三，其余25%来自水力发电。值得注意的是，核能在越南的能源结构中没有任何作用。
另一方面，摩洛哥最依赖水力发电，占比达55%，为四国中最高。化石燃料占43%，核能仅占微不足道的2%。同样，印度高度依赖化石燃料，占65%，其次是水力发电30%，核能仅占5%。
